As ag0aep6g explained, the 'delegate' keyword was not necessary there. A 
case where it's needed is when defining a variable. The following code 
compiles if 'delegate' keyword is present:

void foo(int delegate (int)) {
}

void main() {
     // 'delegate' keyword needed to compile:
     auto f = delegate (int i) => i * 2;
     foo(f);
}
